ANSI/ASME B16.5 Class 900 Carbon Steel Weld Neck Flanges:

ASME B16.5 Class 900 carbon steel weld neck flanges are commonly utilized in high-pressure environments, whether subjected to extreme hot or cold temperatures. These steel flanges are welded around the circumference of the neck, allowing for easy inspection of the butt welded area's integrity through radiography. By matching the bores of both the pipe and the flange, these ANSI B16.5 weld neck flanges help reduce turbulence and erosion within the pipeline. Additionally, they alleviate high stress concentrations at the base of the hub of the ANSI weld neck pipe flange. Consequently, these weld neck flanges are preferred for critical applications. The inside diameter of a #900 weld neck flange is machined to align with the inside diameter of the pipe, ensuring a seamless connection.

Advantages of ASME B16.5 Class 900 Carbon Steel Weld Neck Flanges:

Enhanced Strength: Weld neck flanges possess a lengthy tapered hub that imparts extra strength to the pipe-flange connection. The welding process establishes a permanent and robust bond capable of withstanding high pressures and extreme temperatures.

Versatility in Accommodating Various Pipe Sizes: Weld neck flanges are available in a range of sizes, making them compatible with pipes of different diameters. They can also be utilized with pipes constructed from diverse materials like stainless steel, carbon steel, and alloy steel.

Secure and Leak-Free Connection: The welding process ensures a secure and leak-free connection between the pipe and the flange. This guarantees the safety and efficiency of the piping system by minimizing the risk of leaks and other safety hazards.

Ease of Installation and Maintenance: Weld neck flanges are relatively easy to install, and the welding process can be completed swiftly. They require minimal maintenance, typically involving periodic inspections and upkeep to ensure optimal functionality.

Grades of Carbon Steel Flanges:

American standard carbon steel flanges are flanges made of carbon steel and are widely used in industries such as petroleum, chemical, natural gas, shipbuilding, construction, and water conservancy. Its carbon steel grades are usually divided into the following parts:

1.Q235: Q235 is a commonly used carbon structural steel grade specified in the Chinese national standard GB/T 700. It is often used in general engineering structures and manufacturing industries. In carbon steel flanges, Q235 material is commonly used for pipeline systems operating at low pressure, low temperature, and non-critical stress environments.

2.A105: A105 is a carbon steel material specified in the American ASTM standard, complying with ASTM A105/A105M requirements. A105 material has good weldability and mechanical properties, making it suitable for use in a wide temperature range from low to high temperatures. It is commonly used for pipeline systems and valve connections under high temperature and high-pressure conditions.

3.A350 LF2: A350 LF2 is also a carbon steel material specified in the ASTM standard, complying with ASTM A350/A350M requirements. LF2 indicates low-temperature service, and this material has good low-temperature toughness and crack resistance. It is commonly used for pipeline systems and valve connections under low-temperature conditions.

4.A694 F42/F52/F60/F65/F70: These material grades are specified in the ASTM A694 standard for carbon steel materials used in high-strength, low-temperature, or normal temperature high-pressure pipeline systems and valve connections. Different grades of materials have different strengths and corrosion resistance properties, suitable for various working conditions.

5.ASTM A181 Gr.1/Gr.2: These carbon steel flange material grades are suitable for pressure vessels, valves, and pipeline fittings under low pressure and low temperature conditions. They have good machinability and mechanical performance.

6.ASTM A516 Gr.70: Gr.70 is a commonly used medium carbon steel grade, known for its good weldability and machinability, suitable for manufacturing flanges and pipe fittings, among others.

7.A216 WCB: A216 WCB is a carbon steel casting material specified in the American ASTM standard, complying with ASTM A216/A216M requirements. WCB stands for cast carbon steel, and it is commonly used for carbon steel flanges that require casting in general engineering structures and manufacturing industries.

These material grades mentioned above are only a part of the commonly used ones, and there are other material grades in practical applications. When selecting the material grade for carbon steel flanges, it is necessary to consider engineering requirements, temperature, pressure, medium, and the requirements of relevant standards to ensure that the flange material meets the corresponding performance and safety requirements.
